2 Claims. (Cl. 22161) This invention relates to a cover or' cap for Fig. 3 is a top view of the cap shown in Figs. a dispensing can. 1 and 2.

Dispensing cans are Widely used as containers Referring to the drawing, 10 indicates 'gener- V for powdered substances. As ordinarily conally the body of a dispensing can, which may 7 structed, the can has a body which may be be of any desired size and shape. The can as 60 of any desired size or shape and which is adaptshown is made of thin sheet metal and has a ed to hold a suitable quantity of the powdered top section 11 to which the neck 12 is attached. H substance, while the top of the can is fitted A small flange 13.is formed on the neck 12 with a neck or spout having a Sifter top through where it joins the can. The neck 12 is a short which the contents of the can may be discylindrical sheet metal member having aslight- 65 charged. l 1y convex top portion 14 in which are placed a It is customary to provide a cover or cap plurality of holes 15 through which the con which fits over the top of the neck 01' spout tents of the can are discharged. to prevent spilling of the contents in case the The cap p v d y my inVentiOH is a Small 15 can is accidentally turned over, and this invencup-shaped sheet metal member and is intended tion relates to such a cover or cap. to fit over the neck so as to be held by frictional A cap for this purpose should fit the top engagement. 1 of the can snugly so as to close the holes in the The cap, which is indicated generally by the top, and must be easily removed and replaced. numeral 16, has an annular enlargement or It must be secured in place rigidly enough that skirt 1'? at its open end, so that the cap will fit it will not come off except when intentionally down over the flange '13 at the base of the removed. The cap should present an attractive neck 12. This enlargement or skirt also aids appearance, and since cans of this kind are in placing the cap on the neck, as it is somewhat ordinarily thrown away when empty, it is essenlarger than the neck and helps to center the cap 80 tial that the cap be inexpensive to manufacture. on the neck. Immediately above the portion 17 It has been found impractical to construct is a somewhat smaller section 18 which is prothe cap and the neck of the can to such limits portioned so as to fit snugly around the neck 12 of accuracy that they will always match with and hold the cap in place by frictional engageexactly the proper frictional engagement. The ment. The portion 18 is made of sufficient width result is, that the caps sometimes fit very tightly to permit the ends of the fingers to extend into and it is a difficult task to remove them, espethis portion when the cap is removed. I cially since a cap of this kind is usually of Above the portion 18 is a wide annular ensmall size and difiicult to grasp. larged portion 19 which is suitably knurled or When the cap is removed, it is usually given fluted, as at 20, to provide a gripping area a slight twist in addition to being pulled directly for the fingers.

It will be seen that the cap constructed in accordance with my invention has a wide fluted portion which extends above the closed end and which includes the annular portion surrounding the de'pressed end. This construction permits the-fluted area'to be made much wider than is otherwise possible. furnishes ample gripping surface for the fingers so they will not slip when the cap is being removed. I

If desired, a disc made of any suitable material, such as felt, may be placed inside the cap so that this disc will bear against'the top and close the sifter holes.

When the cap is pushed down on the neck, the

top 21 of the cap fits snugly against the top14 of the neck so as to close the holes 15 and prevent loss of the contents of the can.

The cap provided by my invention is easily removed as it has a large knurled or fluted portion which the fingers can grip so that the cap can. be turnedor pulled off, while there is a depressed portion into which the ends of the fingers can. project so that they can more effectively grip the knurled or fluted portion.

The large gripping area which is provided on this cap makes it an easy matter to remove the cap evenwhen it is tightly secured on the neck.

The cap is easily-replaced as the enlarged portionadjacent the open end helps to align the cap on the neck, so that it is then only necessary to push the cap down on the neck.

The large fluted area In addition, the cap provided by my invention is of simple construction, is inexpensive to manufacture, and has an attractive appearance.

Having thus described my invention, I claim:

1. The combination with a container having an upstanding portion with a convex curved perforatedtop, a removable cap having -a-skirt portion which frictionally engages theupstanding portion, the top of the cap being curved to fit against the curved top of the upstanding portion, the upper portion of the skirt of the cap extending abovethe place where the projected arc of the curved top portion of the cap would intersect the said skirt portion to thereby provide' an extended finger'gripping portion for removalof' said cap.

2. The combination with a. container having an upstanding portion with a convex curved top of continuous surface except for several relatively'smallperforations, a removable cap having a .skirtportion adapted to engage the aforesaid upstanding portion to thereby retain the cap upon the upstanding portion, the top portion of the cap being imperforate and adapted to engage the top surface of the aforesaid upstanding portion substantially throughout the extent thereof, the upper portion of the said skirt of the cap extending above the place where the,

projected top portion ofthe cap would intersect the said skirt portion, therebyproviding-an ex: tended finger gripping portion for removal of said cap.
